Above the curie temperature the susceptibility
of ferromagnetic substance varies

View answer and explanation

Correct option: D

inversely as the absolute temperature

Option D (inversely as the absolute temperature) is correct because, above the Curie temperature, a ferromagnetic substance behaves as a paramagnetic substance, and its susceptibility follows the Curie-Weiss law.

Curie temperature is the one above which A vibration magnetometer consists of two identical bar magnets placed one over the other such that they are perpendicular and bisect each other. The time period of oscillation in a horizontal magnetic field is

{2^{5/4}}

s. One of the magnets is removed and if the other magnet oscillates in the same field , then the time period in second is The relative permeability of a substance
